Army Recognition at RAE Russia Expo Arms 2015

At RAE 2015 (Russia Arms Expo 2015), the Russian Defense Company Machinery & Industrial Groups N.V. Concern “Tractor plants” unveils a new variant of the famous BMP-3 infantry fighting vehicle equipped with a new turret armed with a 57mm automatic cannon AU-220M.

New BMP-3 IFV Infantry Fighting Vehicle fiited with gun mount turret AU-220M armed with a 57mm automatic cannon at RAE Russia Arms Expo 2015 in Nizhny Tagil, Russia.

This new version is based on the chassis of BMP-3 infantry fighting vehicle fitted with a new turret armed with a 57mm automatic cannon using gun mount module AU-220M. A 7,62mm coaxial machine gun is mounted to right side of the main armament. A bank of four smoke grenade dischargers is mounted on each side of the turret.

The vehicle is also equipped with latest generation of computerized firing control system to increase the accuracy of the 57mm cannon. It has the capacity to be used against ground and aerial targets as helicopter and drones.

The 57mm gun with the AP round has a penetration capability of 130mm of Steel at a range of 1.000m.

The AU-220M gun mount system is a remotely operated unmanned turret design to be easily integrated onto modern light infantry fighting vehicles.

The hull and turret of the BMP-3 ICV are of all-welded aluminium armour construction providing the crew with protection from small arms fire and shell splinters. The turret is in the centre of the vehicle with the commander seated on the right and the gunner on the left.

The vehicle can carry a total of 12 military personnel including driver, gunner and commander. The troop compartment is at the rear of the hull with entry via two doors in the hull rear opening left and right, with the left door having a firing port.

This BMP-3 57mm cannon is motorized with a type UTD-29M 10-cylinder 4-stroke liquid cooled diesel developing 500 hp. The vehicle can run at a maximum road speed of 70 km with a maximum cruising range of 600 km.

AU-220M 57mm automatic cannon unmanned turret

The turret is called AU-220. It’s been initially developed as an upgrade to the PT-76 amphibious tank to replace its 76mm main gun and old turret.

An upgraded PT-76 is shown with the 57mm AU-220 turret.

57mm Gun

The 57mm gun that’s also used in Atom 8×8 is basically an Anti-Aircraft gun used in S-60 towed AA system. The gun was developed in 1950’s.

The 57-mm anti-tank gun model 1941 (ZiS-2) developed and adopted in the opening days of the Great World War.

The same cannon also used in ZSU-57-2 Soviet self propelled anti-aircraft gun

Burevestnik’s 57 mm А-220М naval artillery module, from which the AU-220M was effectively reverse engineered.

The cannon uses 57x347mm semi-rimmed ammunition. The image below shows the 57mm ammunition vs the Bofors 40×365 ammunition.

The gun is recoil operated. Rate of fire is 105-120 rpm and the muzzle velocity is around 1.020 m/sec. It has a barrel length of around 4.4m.

The effective firing range against ground targets is 4km’s.

The gun has a new automatic loading capable ammunition feed system that houses 20 ready-to-fire rounds as shown below.

The turret basket has a powered 73 round ammunition carousel that provides ammunition to the linkless feeder above.

The 57mm gun with the AP round has a penetration capability of 130mm of Steel at a range of 1.000m. I would expect the penetration would be much better for the huge 57mm caliber.

The 35mm APFSDS round has 120mm penetration at the same range.
